Quick Summary
Skip the Beaverkill and Willowemoc for trout today. USGS showed the Beaver Kill at Cooks Falls at 141 cfs and 75.4 F during the 9 AM refresh, which is well past the 68 F trout-stress threshold. The Willowemoc near Livingston Manor was 41.3 cfs and 66.6 F, but that low freestone water has very little margin with a sunny forecast near 95 F and a National Weather Service Extreme Heat Warning in effect. If you want to fish around Roscoe today, choose the cold West Branch, another cold tailwater, reservoirs, or warmwater species instead of pressuring freestone trout.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Unsafe for trout on the Beaverkill; not recommended on the Willowemoc because it is low, near the temperature line, and facing another hot afternoon |
| Flow | 141 cfs at Beaver Kill at Cooks Falls; 41.3 cfs at Willowemoc Creek near Livingston Manor |
| Gauge Height | 1.33 feet at Cooks Falls; 1.97 feet near Livingston Manor |
| Water Temp | 75.4 F at Cooks Falls; 66.6 F near Livingston Manor during the 9 AM USGS refresh |
| Clarity | Not reported by official gauges; low clear-looking freestone water can still be too warm for trout |
| Trend | Flows are a little higher than yesterday, but temperature remains the controlling safety issue |
| Best Window | Not recommended for trout today |
| Best Method | Skip freestone trout fishing; use cold tailwater alternatives or warmwater species instead |
| Wadeability | Physical wading may be possible in places, but trout stress makes fishing these freestones the wrong call |
Weather
For Roscoe and Livingston Manor, the National Weather Service has an Extreme Heat Warning in effect and forecasts sunny heat near 95 F, heat index values around 102, and west wind around 2 to 7 mph. A small afternoon shower or thunderstorm chance is possible, but the forecast is mainly hot and bright. The Beaverkill is already too warm in the morning, and the Willowemoc is close enough to 68 F that the safest trout decision is to stay off both freestones.
River Notes
The Cooks Falls temperature decides the report. A 75.2 F morning reading on the Beaverkill is not a short-window situation; it is too warm for responsible catch-and-release trout fishing. The Willowemoc is cooler, but 42.7 cfs is thin summer water and the day will keep heating. Do not use visible bugs, a slight bump in flow, or easy wading as a reason to fish stressed trout. Move to cold release water if trout are the goal, or switch the plan to bass, panfish, reservoirs, or shaded non-trout options.
Hatch Activity
Regional Catskills context still points to a summer mix of sulphurs, Blue Winged Olives, Isonychias, Light Cahills, caddis, dark sedges, and evening spinners. On the Beaverkill and Willowemoc today, those hatches should be treated as seasonal information, not an invitation to fish warm water. Save the trout box for water that is cold enough to fish responsibly.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-18 | Regionally active; fish it only on water that remains safely cold |
| Blue Winged Olive | 18-22 | Small olive activity can happen in dim light, but temperature still controls the trout decision |
| Isonychia | 10-12 | Useful on colder riffle water, not on the warm Beaverkill today |
| Light Cahill | 14-16 | Evening possibility on alternate cold water |
| Tan Caddis | 16-20 | Pupa and soft hackles remain good searching choices only where temperatures are safe |
| Rusty Spinner | 14-20 | Last-light option after a thermometer confirms safe water elsewhere |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Comparadun or Sparkle Dun | 16-18 | Carry for cold tailwater water, not for the warm Beaverkill today |
| Dry | BWO Comparadun or CDC Dun | 18-22 | Small low-light option where temperatures stay safe |
| Dry | Light Cahill or White Wulff | 14-16 | Visible evening fly for alternate cold water |
| Dry | Rusty Spinner | 14-20 | Use only after a fresh temperature check on colder water |
| Nymph | Isonychia Nymph | 10-12 | Good summer nymph in cold riffles away from stressed freestone trout |
| Nymph | Pheasant Tail or Frenchie | 14-18 | Mayfly nymph for tailwater seams and pocket water that remains cold |
| Nymph | Caddis Pupa | 16-18 | Work riffles and pocket water on safer alternatives |
| Other | Stream Thermometer | Not reported | Required in this heat; stop targeting trout whenever water approaches 68 F |
Tactics
Do not fish the Beaverkill for trout today, and do not assume the Willowemoc will hold a safe afternoon window. If you are already in Roscoe, redirect to the cold West Branch, another tailwater, reservoir edges, or warmwater species. If you check any trout water yourself, take the temperature before fishing and keep checking as the day warms. Stop before 68 F, land fish quickly where water is safe, and avoid adding stress to fish that are already riding out extreme heat.
